toturn 4on the pedestal about `'the' shoulder s L1A ball bearing 8 is interposedfbetween the shoulder andthe bottom .of the lantern. 4The bottom ,7 of the lanternf hasan annular chambergfl." *The lantern comprises atop 10 supportedfrom the bottom, 7, l1' which are' secured in vboth` the top 10 and the bottom Upwardly-extended, `diverg.- ing arms `12 are by hollow `posts thetop "10. The s are secured tolthelarms 12, at points near to the outer endsfof the arms,each chainbeng mounted "at its upper end on one of theanchor hooks 14.1 In their inner surfaces, the- [d `secureflto theredgeofthe"` bottom 7L Anchorfhooks 14 are mounted on j lower end of stay chains 15 `arms 12 have longitudinal grooves 16.` Cover strips 17 `are mounted on the inner edges of y l the farm-s and Vconvert the groovesl. into passages inthe arms.A Sockets 18` are mounted on theouter ends of the lamps 1'9hare carried by the sockets 18. u The top A10` has an upstanding, annular "rim 20,

about which fits a cap 21 supportedon the top10. The top 10 has ashoulder22located v withinthe rim20. On the shoulder 221s searms `12.` Electric t l cured a crossbar` 23, preferably made of metall Inlthe` cross bar 23 is .s received the squared end `2li of a vertical shaft 25extended downwardlythrough the pedestal 3, the shaft beillsioulrlald at `its `lower enlfin` a, bearing 26 mountedonthesbase -1 within the recess,` s d r securedl to thelower end ofthe shaft 25. 5

pinion 28 on ahoribase land in `bearings 3Q carried by the base 'and locatedin therecess `2. vAny suitable means, however, ing the shaft 25.4 upper `surface *of the head `5 there are seats or notches 31, which can be seen,als`o, inV Figure 2. `The seats 31 are adapted to rerhe beveled gears-27 may be employed `for rotat- Figure 4: showsthatin the ceive pins `32 which projectffromfa lower insulating .block33 supported withinthe head 5. `A bearing 34of tubular form is journaled f 33 and is securedat 35 tothe in the block d d shaft 25,]the bearing34receiving the shaft 25. A. lball bearing 36 is disposed `about the `-insulating block 33 `and `isinterposed between the head-5 and the top 10 of the lanliu tern, to aid in supporting the lantern antifrictionally for rotation on the pedestal. The lower insulating block 33 has an upstanding rim 37, within which extends an upper insulating block 38. The bearing 34 extends up into the upper insulating block 38 and aids in keeping it centered. A bridge bar 39 is secured to the upper insulating block 38. 'Ihe squared end 24 of the shaft 25 extends upwardly through the bridge bar 39, and, therefore, when the shaft 25 is rotated, rotation will be imparted to the upper insulating block at the same time that rotation is imparted to the top 10 of the lantern.

An outer conducting ring 40 is mounted on the lower insulating block 33. An inner conducting ring 41 is mounted on the lower insulating block 33. An outer conducting ring 42 is mounted on the upper insulating block 38. An inner conducting ring 43 is mounted on the upper insulating block 38. rIhe inner conducting ring 43 bears slidably on the inner conducting ring 41 and the outer conducting ring 42 bears slidably on the outer conducting ring 40. A compression spring 44 surrounds the squared end 24 of the shaft 25. The upper end of the spring 44 engages an abutment 45 on the part 24 of the shaft 25. The lower end of the spring 44 presses downwardly on the bridge bar 39. The purpose of the spring 44 is to press down the upper insulating block 38, so that the ring 42 has a good electrical contact with the ring 40, the ring 43 having a corresponding contact with the ring 41. There are binding posts 4G on the lower insulating block 33, the posts extending downwardly into the hollow head 5. The binding posts 46 are in electrical engagement with the conducting rings 4() and 41. Conductors 47 are connected to the binding posts 46. The conductors 47 extend downwardly through t-he hollow pedestal 3. Binding posts 49 are mounted on the upper insulating block 38 and are in electrical connection with the rings 42 and 43. Conductors connect the binding posts 49 with thelamps 19.

In practical operatiomwhen the shaft 29 is rotated, the beveled pinion 28 and the beveled gear 27 will rotate the shaft 25. The shaft 25 will rotate the lantern 6, because the squared end 24 of the shaft 25 is received in the cross bar 23 that is attached to the top of the lantern. The squared end 24 of the shaft also rotates the upper insulating block 38, because the end 24 of the shaft is received in the bridge bar 39. When the lantern 6 is rotated the lamps 19 will be carried around in an orbit, with a pleasing effect which can be taken advantage of for advertising, and for many other purposes, in the home, as well as in public. It will be obvious that since the rings -42 and 41-43 are in slidable contact with each other, the lantern 6 can be rotated, as aforesaid, Without break-- ing the continuity of the lamp circuit.

Having thus described the invention, what is claimed is:
